The mathematical forms of order which the mind of a physicist manipulates coincides "miraculously" with experimental measurements. - Marie-Louise von Franz

To sum up: numbers appear to represent both an attribute of matter and the unconscious foundation of our mental process. For this reason, number forms, according to Jung, that particular element that unites the realms of matter and psyche. It is “real” in a double sense, as an archetypal image and as a qualitative manifestation in the realm of outer-world experience.

Number, as it were, lies behind the psychic realm as a dynamic ordering principle, the primal element of which Jung called spirit. As an archetype, number becomes not only a psychic factor, but more generally, a world-structuring factor. In other words, numbers point to a background reality in which psyche and matter are no longer distinguishable.

…Jung even asserted that he would have no objection to regarding the psyche as a quality of matter and matter as a concrete aspect of the psyche, provided that the psyche was understood to be the collective unconscious.
